Hi All, I installed the latest Dolphin-emu version 5.0.3 via pkg upgrade today. Unfortunately Dolpin doesn't start. (core dump) Dolphin 5.0.r_2 works without any problems. Cheers, Christian
Hi, Have you tried starting off a new configuration ? Try to move (or remove) ~/.config/dolphin-emu and start dolphin again. If it still dumps core, can you post a backtrace or a log message ? Best regards, Ganael.
Hi Ganael, Many thanks for your fast reply! :-) The config directory of Dolphin is in the home directory directly. I renamed it but unfortunately it doesn't work either. gdb /usr/local/bin/dolphin-emu GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

Hmmm, nothing very useful here. It seems to have crashed while loading a shared library. I cannot reproduce the problem on my machine (FreeBSD 11.0-RELEASE-p2, amd64) with Dolphin installed from packages. On what FreeBSD version / arch are you trying to run it ? Also, are all packages' dependencies up to date ? Can you try to rebuild Dolphin from ports to see if it still crashes ? You can enable debug symbols to produce a (hopefully) more detailed backtrace : # cd /usr/ports/emulators/dolphin-emu # make WITH_DEBUG=yes install Best regards, Ganael.
I run it on FreeBSD 10.3-RELEASE amd64. Yes, all packages' dependencies are up to date. I compiled it with debug symbols today. run Starting program: /usr/local/bin/dolphin-emu [New LWP 100234] warning: Lowest section in /usr/local/lib/libicudata.so.58 is .hash at 0000000000000120 Program received signal SIGSEGV, Segmentation fault.

It does not seem to be related to Dolphin itself, but to OpenGL and more precisely to the (proprietary) nvidia driver. I have found the same kind of backtrace here : http://pastebin.com/6VA42etE Can you run glxinfo without any problem ? I imagine you can run Dolphin-emu with : $ env LIBGL_ALWAYS_SOFTWARE=yes dolphin-emu Have you tried contacting Nvidia ? Another option would be to ask on Dolphin forums, maybe they are aware of instabilities/bugs related to that driver. Hope this helps... Best regards, Ganael.
Yes, glxinfo works without any problems. glxinfo | grep -i opengl OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GTX 680/PCIe/SSE2 OpenGL core profile version string: 4.5.0 NVIDIA 367.44 OpenGL core profile shading language version string: 4.50 NVIDIA OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 4.5.0 NVIDIA 367.44 OpenGL shading language version string: 4.50 NVIDIA OpenGL context flags: (none) OpenGL profile mask: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 367.44 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20 Unfortunately 'env LIBGL_ALWAYS_SOFTWARE=yes dolphin-emu' doesn't work either. (core dumped)
Digging into that problem a bit further reveals other seemingly-related PRs : https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205149 (and https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206899) https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=186565 and also that discussion : https://lists.freebsd.org/pipermail/freebsd-threads/2015-December/005807.html In short, Nvidia driver seems to have a problem when the main application linking to LibGL also links to another library that links to libthr. One fix seems to be to link the main application to libthr too. I'll prepare a patch for you ASAP to test that fix. Best regards, Ganael.
Created attachment 178842 [details] Test patch Hi, Can you try the attached patch ? Just copy it to the files/ folder of the port and rebuild dolphin-emu. It implements both fixes suggested in PR #205149 : - It links to OpenGL libs earlier - It explicitly links the main application to libthr I don't know if that will fix you crash. It is quite difficult to debug the problem because I cannot reproduce it myself (I don't have a Nvidia card). If that does not work, have you checked if that problem occurs with the nv driver ? Also, as a last resort, have you tried to raise the problem on freebsd-x11 or freebsd-threads lists ?
Dolphin works with your patch! :-) I tested it with a Wii game and a GameCube game today. Fantastic! Well done! Thank you very much!
Created attachment 178893 [details] 2nd test patch (thr only) Good news, thanks for your feedback. The previous patch implements both suggestions from PR #205149 : - linking to OpenGL libs earlier - linking the main application to libthr but linking to libthr should be enough. May I ask you to test another (simpler) patch ? Could you replace the previous patch in the files/ directory of the port by the new attached patch, rebuild and reinstall Dolphin and tell me if it is enough to fix the problem ? Best regards, Ganael.
I compiled Dolphin with your 2nd patch today. Unfortunately Dolphin doesn't start. (core dump)
Created attachment 178903 [details] 3rd test patch (link order only) Good, so I presume only the link order is relevant here. Can you confirm this and test that (last) patch ? Thanks a lot :)
Dolphin works with your 3rd test patch. :-) Many thanks for your work!
